Think on This......my take

Pandrea's take on the three most important things to see in HBP:
1.   Snape's history and why he changed sides;
2.   Why Godric Gryffindor and Salazar Slytherin fell out;
3.   Sirius's mirror.

My take, in no order of importance;
1.   Voldemort's history, if there is one, with the Evans's and Potters;
2.   The backstory of the Evans and Potter families;
3.   The future of the Minstry and wizard government in the War.
